At present, air conditioning connections are basically connected by bifurcated pipes. Why did mitsubishi electric use a forked box? Can you explain the advantages of bifurcated pipe over bifurcated box? Bifurcation is relatively simple, just like the three-way nature of water pipes; The distribution manifold, which is also used for the warm manifold box, connects the pipes of the air-conditioning host to the two main interfaces on the right in the figure, and then the five-way (one in and one out) interfaces on the left are connected to the internal machines respectively.

The advantages of adopting bifurcated pipes are:

1, the price is cheap;

2. During installation, the pipeline will not be excessively concentrated, so the punching will not be very concentrated, and the damage to the beam is relatively small.

The relative disadvantages are:

1, the refrigerant distribution balance is not as good as that of manifold;

2. On-site welding is required, which is easy to cause human error, and welding slag enters the pipeline to damage the compressor.

The advantages of using the furcation box are as follows:

1, the refrigerant distribution is relatively more balanced;

2. The pipeline does not need to be welded, which reduces human error and avoids the harm of welding slag entering the compressor.

Disadvantages are: higher price; Too concentrated pipes will do great harm to the light beam.

Advantages and disadvantages are not absolute.

If the location of the branch box is not well selected, some internal pipelines are short and some internal pipelines are long, it will be unbalanced; In addition, air conditioners are rarely turned on at the same time, so it is difficult to reflect the balance. The electronic expansion valve of air conditioners has strong adjustment ability, and thousands of gears can basically be adjusted. If the location of the branch box is chosen well, the pipeline will not be too concentrated.

In fact, there are not only two installation schemes for the central air conditioner of fluorine system, but also for the central air conditioner of water system. One is to open a three-way water pipe; The other is to use a hydraulic balance distributor, which is the same as the floor heating distribution manifold. In the field of water system central air conditioning, you can choose two schemes freely, while in the field of fluorine system central air conditioning, you can only choose one way.

Except for the bifurcated box in mitsubishi electric, other brands basically adopt the installation method of bifurcated pipes. Of mitsubishi electric's four series, only Lingyao and Bingyan series adopt bifurcated boxes, while Ling Rui and Shanling do not. Among them, Ling Rui adopts bifurcated pipes.
